Hi,

1) SRM transaction are carried out using ITS (internet transaction server) transactions ie internet based , which is not possible by SAP MM.

2) Capturing the requirements at higher level (for example material group level) and auto process of purchase orders are possible in SRM , which is not possible in SAP MM

3) At high level it is very industry friendly for indirect materials (i mean where we can't have stocks ) procurement compared to SAP MM .

4) SRM needs a backend system for financial posting . this is a minimum requirement .SRM won't support Finance transactions.

5) In case , we have SAP ECC or R/3 system , the functionalities in SRM and ECC can be leveraged to the maximum possible .

6) Back end system and SRM system are connected by defining logical systems and the interactions will happen by various means for example RFC calls, BAPIs, IDOCs etc.

All advantages of using SRM and MM module is in Plan-Driven Procurement documentation on service.sap.com/instguides -> SRM.

Generally planning in APO or MRP in an ERP system calculates the quantity and materials required. This requirement can be transffered to the EBP system. Requisitions from SAP Plant Maintanance or Project System are also possible requirements.

The requisitions are passed to EBP. If the data is complete and unique, purchase orders can be created automatically. If the data is missing, the proffesional purchaser has to complete the missing information in Sourcing or via Process Purchase Orders. An option for the professional buyer is to assign un-sourced PO to an RFQ and send it out for bids.

The proffesional purchaser completes the orders, assings source of supply, add or deletes item.

Once the order is complete it is issued automatically to R/3. XML is the upcoming medium, since the data can be automatically integrated in more and more supplier's systes, or You can send orders by e-mail, fax or print them.

Goods receipt is either done in EBP by supplier via an XML confirmation, by employee who requested the item by general goods recipient or in the backend system. Inventory is updated in backend.

The invoice is processed in EBP manually by the requestor or an accountant submitted by the supplier via an XML invoice, possibly from SUS or backend system.
